Question
Studies have shown that individuals with attention deficit hyperactivity disorder (ADHD) may have lower than normal amounts of dopamine and norepinephrine excitatory neurotransmitters in their synapses. Methylphenidate is one of the drugs prescribed to individuals with ADHD. It prevents the reuptake of dopamine and norepinephrine neurotransmitters from the synapses, thereby keeping these neurotransmitters in the synapses longer.
